Rayonism☀️, hacking the Merge collectively
This week, protolambda and others launched plans for Rayonism, an formidable month-long hack to create Merge devnets based mostly on present specs with a stretch aim of including sharding to those devnets together with L2 rollup integrations.
The first motivation is to unite growth round a unified Merge spec to onboard all consumer groups firmly into the Merge design and course of in order that an knowledgeable determination on the Merge roadmap could be agreed upon within the coming months. That, and have slightly little bit of enjoyable 🙂
Along with Rayonism, Merge specs and design paperwork are making nice progress. Enormous shout-out to Mikhail and to the numerous reviewers and contributors pushing this alongside!

blst safety advisory
Yesterday, Supranational launched a safety advistory for the blst BLS library that’s presently in use in manufacturing by all beacon chain shoppers in the present day.
In the course of the course of differential fuzzing of the blst library by Guido Vranken, he found that blst can produce the wrong outcome for some enter values within the inverse perform. This was patched in a blst launch three weeks go and has been launched into all beacon chain shoppers.
Though there’s presently no recognized sensible exploit of this challenge, it’s suggested that everybody working beacon chain shoppers improve to the newest model in case an exploit is uncovered. Equally, in case you use blst in your mission, we extremely suggest bumping to the newest model as quickly as doable.
[Note: Teku was not running an affected version of blst, but they have some juicy optimizations recently so you might as well upgrade anyway]
You may learn extra about this challenge within the public safety advisory on the blst repo.
Beacon Chain safety+testing RfP
Reminder! There’s an excellent Beacon Chain safety+testing RfP.
The EF is in search of any proposals that additional the safety and robustness of the Beacon Chain and the upcoming merge (migration from PoW to PoS). Dwell community evaluation, formal verification, consumer load testing, new consensus vectors — simply to call a couple of potential paths.
Get artistic! Given you and your staff’s skillset, there’s doubtless a helpful strategy to contribute to the safety of this method.
Proposals are due April twentieth 🚀
